The raise at start was the only place buckets were asserted, so a module
registered and assigned since had none until the control plane restarted —
found on the first module to declare state.
A manifest names the state it keeps (state) and reads (reads); the controller
asserts a key-value bucket per name on every raise, grants owners write and
readers read (measured against a running server), issues each assignment its
buckets in the membership, and reports buckets nothing declares without
removing them.
